T-80UD Main Battle Tank â€“ A Pakistani Perspective January 4, 2013 8:10 pm 2 comments Share this Article Twitter Facebook Delicious Digg Stumble Reddit Author: Damian The T-80UD main battle tank is currently the most advanced and best protected tank in Pakistan armed forces arsenal. Designed during the second half of 1980â€™is in KMDB (Kharkiv Morozov Machine Building Design Bureau) as alternative to T-80U (Object 219AS), the T-80UD (Object 478B) it was the most advanced tank fielded back then for Soviet forces. Differences between T-80U and T-80UD are not big, however important. T-80U is powered by GTD-1250 Gas Turbine engine, generating 1,250HP, while T-80UD is powered by compact Diesel 6TD, generating 1,000HP. Another difference is tank commander cupola. T-80U have simpler cupola without heavy machine gun mount, HMG is mounted on simple pintle mounts (4) welded to turret roof in several positions. While T-80UD have more advanced cupola with remotely controlled HMG operated by commander from tank interior even when hatch is closed.
